The Reality of our first Free Body Diagram
The free body diagram we first learn is not entirely accurate. All of the forces are not drawn from the center of mass of the object. Learn why we start this way and, when we get torque, what the free body diagrams will actually look like.

Piezo Power Under pressure, crystals live up to their electric potential
Some materials generate an electrical potential when they’re mechanically stressed. This ability to convert mechanical energy into a tiny jolt of electricity (or vice-versa) is called the piezoelectric effect, and engineers have been...
